Pregnant women can safely eat most edible mushrooms as long as they are fresh, properly washed, and cooked. Mushrooms like button, oyster, straw, shiitake, maitake, and portobello are generally safe and provide valuable nutrients including B vitamins, vitamin D, iron, fiber, antioxidants, and protein beneficial to both mother and baby. However, pregnant women should always avoid raw mushrooms, wild or toxic mushrooms, and psychoactive (magic) mushrooms due to risks of food poisoning or harmful effects. It is also important to buy mushrooms from trusted sources and watch for any allergic reactions. Consulting a doctor before consumption, especially for medicinal mushrooms or mushroom extracts, is recommended. This makes mushrooms a nutritious and safe addition to the pregnancy diet when prepared correctly.
